A report published by the Clean Air and Sustainable Environment (CASE) Project under the Department of Environment showed that the AQI of Dhaka stood at 387 on January 28, 2018. The index terms the air quality of Dhaka is extremely unhealthy, as the city consistently ranks between 301 to 500 range. Commenting on the matter, Md Ziaul Haque, director (Air quality management), Department of Environment said: "There is no denying that the quality of air in Dhaka is quite terrible. The air quality started dropping since October, 2017. "At least a thousand brick kilns step up production in and around the city during winter and that is one of the reasons behind the bad air quality here." The United States Environmental Protection Agency (EPA) developed the Air Quality Index to report air quality. This AQI is divided into six categories, indicating increasing levels of health concern. An AQI value over 300 represents hazardous air quality and below 50 the air quality is good. The index is based on the five criteria pollutants regulated under the Clean Air Act-- ground-level ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide. The AQI debuted in 1968, when the National Air Pollution Control Administration undertook an initiative to develop an air quality index and to apply the methodology to Metropolitan Statistical Areas.
